The elevated bowl can reduce stress on small pets' joints and spine to lower the risks of arthritis..Clog-Free Design: The motor reverses when blocked, which reduces the food jam significantly. The dry, mixed, and air-dried food (only dry food) in 3-18mm is compatible with the auto pet feeder.

If you have a short trip, no worry that your pet will be hungry. Switch the single or double bowl anytime that furry friend in two-pet families can share the food equally and won't fight..Dual Power Supply: Your pet will never miss a meal. It is recommended that use the USB power cord to maintain the power supply since the batteries only support for 2 months. The three D-type batteries are for the backup power supply. (WARM TIPS: The batteries should be prepared by yourself.) The feed schedule and current time you set before will save via the backup power of batteries, even if there's no power. When power is back, you don't need to set it again, which saves time and effort.
